Integra Biosciences Pipette Tip 1250 ul Sterile 20 Rack Inserts - 1920 Tips

Integra Biosciences 4446 GripTip Pipette Tips – 1250 µL, Green Choice Inserts, Sterile

The Integra 4446 is a specialized 1250 µL (1.25 mL) pipette tip engineered exclusively for use with Integra's advanced line of manual and electronic pipettes. Featuring the proprietary GripTip system, these tips provide a flawless, secure seal that will never loosen, leak, or fall off during critical high-volume liquid handling procedures. This specific 4446 catalog number is part of Integra’s "Green Choice" initiative, providing environmentally friendly, pre-sterilized tip inserts designed to be loaded directly into reusable empty tip racks. Molded from 100% virgin polypropylene in a highly controlled cleanroom environment, they carry the VIAPURE certification, guaranteeing absolute sample purity and precise volumetric delivery without generating excessive plastic waste.

Technical Performance and Design

• Proprietary GripTip Snap-On Design: The specialized rim securely locks over the multi-lobe pipette fitting, completely eliminating the risk of tips physically detaching or leaking fluid over expensive microplates or deep-well blocks.

• Positive Stop Shoulder: Features an engineered internal shoulder that acts as a physical stop. This ensures every tip across a multichannel pipette is loaded at the exact same height and perfectly aligned for ultimate precision.

• Green Choice Refill System: The eco-friendly packaging utilizes lightweight plastic inserts that drastically reduce plastic waste by over 60% compared to purchasing standard racked tips, significantly lowering the carbon footprint of your laboratory.

• High-Purity Polypropylene: Molded from premium virgin polypropylene, the smooth internal surfaces minimize unspecific fluid binding, ensuring maximum sample recovery of biological buffers and large-volume reagents.
